C語言中IP地址格式轉(zhuǎn)換?
IP地址為xxx.xxx.xxx. 這個(gè)程序是把二進(jìn)制數(shù)轉(zhuǎn)換成十進(jìn)制數(shù),也就是把一個(gè)32位的數(shù)轉(zhuǎn)換成十進(jìn)制數(shù)輸出,第一個(gè)二進(jìn)制數(shù)被分成四個(gè)整數(shù),每個(gè)整數(shù)有八個(gè)數(shù),而bindec()就是把二進(jìn)制數(shù)轉(zhuǎn)換成十進(jìn)制數(shù),并用遞歸調(diào)用得到它。這里是為了(I=0i2*binudec(2,6)-->2*binudec(2,5)-->2*binudec(2,4)-->2*binudec(2,3)-->2*binudec(2,2)-->2*binudec(2,1)-->2*binudec(2,0)反向推導(dǎo)bin,如果dec(2,7)=255,那么IP:255xxx.xxx.xxx
